Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on custom AI assistant trained on your technical content, and surfaces documentation gaps via analytics caught me off guard. Answer quality depends on documentation quality is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Use it every day

Honestly didn't expect to like it this much. Source citations in generated answers is exactly what I needed, and grounded in your own sources, reducing hallucinations. I do wish limited value outside developer-focused use cases, but I reach for it almost every day now and it just clicks.

Years in this space

I've evaluated a lot of these over the years. What stands out here is source citations in generated answers — handled better than most — and saves developer support and DevRel time. Limited value outside developer-focused use cases is my one real gripe. Worth the time if this is your use case.
